Key Features

  • High-Torque Performance: The 12-tooth configuration provides a lower gear ratio, significantly increasing "grunt" for better low-end acceleration and easier hill climbing.
  • Heavy-Duty 428 Compatibility: Precision-engineered to fit 428-pitch chains, which are thicker and stronger than standard 420 chains, making it ideal for larger 140cc–160cc engines.
  • Steel with Hot-Treatment: The steel is thermally hardened to provide extreme surface density, ensuring the teeth resist the "hooking" or rounding often caused by high-stress off-road riding.
  • Complete Installation Kit: Each sprocket includes a free locking plate (holder) and mounting bolts, ensuring you have everything needed for a quick and secure installation without searching for spare hardware.
  • Universal 17mm Fitment: Designed to fit the most common output shafts on Chinese-made horizontal and vertical engines, with standard 30mm bolt spacing for wide compatibility.
